HRN 467: Ode to a Decibel

A decibel is 1/10 of a Bel. By rights, this should be 1/10 of a show, but it’s at least 1/3. So bonus.

Well, at least we didn’t resort to an Ask Me Anything 🙄. Instead, Jim NO1PC and David W0DHG scraped Gary K4AAQ’s Facebook feed for Elmer questions that he answered in his usual “here’s how to build a clock” complexity. Or not! The dB answer was an attempt to simplify, to explain decibels without any math. Almost no math. Because Gary doesn’t know the math. He does it all by remembering 3 dB and 10 dB. Everything else slides between those two markers.

Then there’s a dual band antenna mystery to solve, some background on just how unique your call sign is, and a review of tone decode. All with a low grade fever.
